Question

if the angles (13 x + 30) and (5 x + 6) are supplementary angles , find the measure of these angles​

Answer 1

Answer:

I thing so the answer is 43 and 11

Answer 2

Supplementary means their sum is 180°. (13x+30)°+(5x+6)°=180° 13x°+30°+5x°+6°=180° 13x°+5x°+30°+6°=180° 18x°+36°=180° 18x°=180°-36° 18x°=144° x=144°/18° x=8 (13 x + 30)°=(13×8+30)° =(104+30)° =134° (5 x + 6)°=(5×8+6)° =(40+6)° =46°
